At Striueling , 27 Jul

In Blaeu’s Coila Provincia (1654) it appears in the form Kraig Darroch –
Craigdarroch farm nestles at the base of the north face of Craigbraneoch Hill between Blackcraig Hill to the east and Craigdarroch Rig to the west.
Gaelic creag darach ‘rock of the oak’
The Ordnance Survey Name Book (1855-57) entry for Craigdarroch reads –
Craigdarroch: A farm house occupied by John Welch, senior. herd, the property of Mr. John Craig, Polquheys.
First element: Gaelic creag ‘rock, crag’
The place-name element craig– is very common in the parish of New Cumnock and is either Gaelic creag ‘rock, crag’  or Scots craig ‘rock, crag’ .
In the case of Craigdarroch the first element is readily identifiable as Gaelic creag ‘rock, crag’ . Identifying the rock in question is a little more tricky. There are no named rock faces going by that name of the nearby Craigbraneoch Hill or Blackcraig Hill. Nor is there one on Craigdarroch Rig, albeit it terminates on its northern face with a rock face known as Bolt Craig (known locally as ‘The Bout’)  – perhaps this was the original ‘rock of the oak’, which it gave its name to the Rig and the farm.
Second element: Gaelic darach ‘oak-tree, oak-wood’
As noted in the Ordnance Survey Name Book (1885-57) entry for Craigdarroch Rig, the second element is Galeic darach ‘oak-tree, oak-wood’ . Presumably the oak-tree or wood is long gone.
Place-Name Craigdarroch + Scots rig ‘ridge’
The Ordnance Survey Name Book (1855-57) entry for Craigdarroch Rig reads –
Craigdarroch Rig: A high ridge extending from Yarngallows Knowe to Bolt Craig.
darach ‘an oak, oak timber’ and dearg ‘red’ – Gaelic Dictionary
rig, rigg ‘a ridge’ – Jamieson, i.e. Jamieson’s Scots Dictionary
Scots rig ‘A ridge of high ground, a long narrow hill, a hill-crest’ .
Oak Trees, Druids and Christianity
Shirley Toulson in ‘The Celtic Year’  explains, ‘Druids made their temples in oak groves, where the trees supported the sacred mistletoe, and where the oak apples could be ground into a flour that appears to have been used in a ritual meal.’
Some commentators believe the druids take their name from Greek drys ‘oak’. There is no evidence of an ancient grove at Craigdarroch, but what a stunning location for a sacred, spiritual place. Sacred associations of oaks survived the advance of Christianity perhaps the most notable Celtic examples being in Ireland at St. Brigit’s* foundation at Cilla Dara ‘church of the oak’, i.e. Kildare and St. Colum Cille’s (Columba) foundation Doire Calgaich ‘Calgaich’s oak grove’, i.e. Derry.
